If a user attempts to access these webpages after this
date/time, automatic redirects will occur. This change is required since
the Java applet will no longer properly function with Java Release 9. As
the Java applet has evolved, its Application Programming Interface (API)
has also changed, to the point where it can no longer be reliably used
since it significantly degrades Web browser performance and must be
deprecated.

The Aviation Digital Data Service
(ADDS) makes available to the aviation community text,
digital and graphical forecasts, analyses, and observations of
aviation-related weather variables. ADDS is a joint effort of NCAR
Research Applications Program (RAP),
Global Systems Division (GSD)
of NOAA's Earth System Research Laboratory (ESRL), and the National Centers
for Environmental Prediction (NCEP)
Aviation Weather Center (AWC).
